Overview

This chapter demonstrates how trigonometric ratios learned in the previous chapter are applied to solve real-world problems involving heights and distances. We learn to use angles of elevation and depression to calculate measurements that would be difficult or impossible to measure directly, such as

Key Concepts

The straight line drawn from

The straight line drawn from the eye of an observer to the point being observed on an object. This forms the basis for all height and distance calcula

The angle formed between the line

The angle formed between the line of sight and the horizontal when looking UP at an object above eye level. Example: Looking up at the top of a buildi

The angle formed between the line

The angle formed between the line of sight and the horizontal when looking DOWN at an object below eye level. Example: Looking down at a car from a bu

Step

Step-by-step approach: 1) Draw a clear diagram showing the situation, 2) Identify given information (angle, known distance/height), 3) Identify what t
